Answer:

The circuit is said to be closed

Explanation:

Electricity is defined as the movement of electrons within a conductor in a certain path.

This means that, for electricity to flow, two conditions need to be fulfilled:

1- there must be conductor materials for electrons to move through

2- a closed path (loop) must exist to allow the flow of electrons

If wither of these conditions is not met, the movement of electrons will be stopped and therefore, electricity will not be conducted

Based on the above, when all parts of a circuit are composed of conducting materials (conductors forming closed path), the circuit is said to be closed (a loop exists for electrons to move in).

Hope this helps :)
